This is the first DIY Wii Sensor "bar" that I experimented with. I don't think I'm supposed to end a sentence with the word with. I've done it again.
I figured I should take a couple pictures of this one since it is being disassembled and recycled into another new sensor bar model.
For a first attempt, this one worked rather well, though only having a single LED per side meant that it wasn't very forgiving when you weren't in the center, facing the screen head on.

Mark (narrowcurves) created Sensor Enclosure in wonderful detail and then uploaded it using 3DVIA Composer. Check out the immaculate board components and wiring! That level of attention to detail makes a big difference when it comes to assembly. Very nice!

El lago Chad (del francés: Lac Tchad) es un lago endorreico poco profundo que se encuentra situado en la frontera entre Chad, Níger, Nigeria y Camerún, en África. Su capacidad ha ido menguando con el paso del tiempo y debido, sin duda, a la desertización provocada por la cercanía del desierto del Sahara y por la captación de aguas para irrigación de cultivos. Se ha calificado como uno de los mayores desastres medioambientales ocurridos en la historia reciente, semejante al del Mar de Aral en Asia. (es.wikipedia.org/wiki/Lago_Chad)
El índice diferencial de humedad normalizado o NDMI detecta los niveles de humedad en la vegetación utilizando una combinación de bandas espectrales del infrarrojo cercano (NIR) y del infrarrojo de onda corta (SWIR). Es un gran indicador del estrés hídrico en los cultivos.
En color azul oscuro se muestran los mayores niveles de humedad. El color rojo corresponde a suelos estériles, secos.
The normalized difference moisture Index (NDMI) is used to determine vegetation water content and monitor droughts. The value range of the NDMI is -1 (red) to 1 (dark blue). Negative values of NDMI (values approaching -1) correspond to barren soil. Values around zero (-0.2 to 0.4) generally correspond to water stress. High, positive values represent high canopy without water stress (approximately 0.4 to 1).
Overview
PIR sensors allow you to sense motion, almost always used to detect whether a human has moved in or out of the sensors range. They are small, inexpensive, low-power, easy to use and don't wear out. For that reason they are commonly found in appliances and gadgets used in homes or businesses. They are often referred to as PIR, "Passive Infrared", "Pyroelectric", or "IR motion" sensors.

FAQ
1.How long do motion sensor lights stay on?
Most people set their motion detection lights so they will stay on for about one to two minutes.
2.Do motion sensors save electricity?
Motion sensing switches do have some “phantom” energy use. According to this study, motion sensor switches use about a watt of energy on standby mode (23 hours a day) and 5 watts on active mode (about an hour a day). This trims a bit off of your overall savings.

Background:
A while back I brought my Wii with the prototype sensor bar over to my sister and her family's place to play some games while my sister was at her baby shower. Predictably, they got addicted and the search began. They purchased a Wii for xmas, and asked if there were aftermarket sensor bars available (to take their console to friends' houses, etc), or if they had to rig something up like my crazy contraption. So, seeing as we're pretty much broke these days, I figured the cheapest thing I could do was make a spare sensor bar that they could cart around. So, the search for a good housing began.
Heather found a 2-pack of ~10-inch long drawer pulls in Ikea's scratch'n'dent area for a buck!
Perfect!
So, this pic is a shot of the drawer pull strapped to the bench, getting the first holes drilled.
Note the high tech clamps.
Cost so far: $0.50
New sensor arrangement. Having sensors in all four corners didn't get me all that much data, so here they are at 6" intervals along the radius of the pile.
What the piss happened to my sensor?! This has never happened before. I bought a cleaning kit and cleaned it myself. It took ages though. I hope this never happens again!
the rain has made non-ripple patterns in the sand... i am not sure how i feel about this, as i am very fond of ripples in sand
Our unique light sensor measures the intensity of the room's light and automatically calibrates the brightness of the image on the screen. In a sun-filled environment, the picture grows even brighter, and in dim surroundings, intensity is reduced. So now you're saving energy on a bright screen when it isn't needed. You're enjoying the best picture possible with a TV that's aware of its surroundings.
The resistivity of the water after filtration can be measured in the hundreds of MΩ—very close to theoretically perfect resistance for water. This machine records with two probes, just like a normal DMM.
